A review of the recent research progress in the determination of trace amount of iron with catalytic-kinetic spectrophotometric method is presented and discussed in the present paper. Firstly, by comparison it is showed that catalytic-kinetic spectrophotometry has more advantages than atomic absorption spectrophotometry and extraction spectrophotometry for the determination of trace amounts of iron. Then the basic theory of catalytic-kinetic spectrophotometry is introduced. The review and discussion for the recent research developments of the catalytic discoloring spectrophotometry, catalytic coloring spectrophotometry, the catalytic coloring-inhibition spectrophotometry, and the catalytic discoloring-inhibition spectrophotometry for the determination of trace amounts of iron are suggested respectively. Finally the development trends and application perspectives for the catalytic-kinetic spectrophotometry in the future are discussed.
